doing a quick google search for xrandr fix overscan is returning a lot of links,
(some good, some not as usual)
see if your setup supports
xrandr --output <output> --set underscan on
other than that, you need to set your resolution that X uses to something
smaller than the actual screen, and then reposition the portion that X uses on
the actual display
I see the folloing in one of the links I followed
Could try a overscan correction with xrandr
Assuming the sad 1024x768 resolution..
Code:
xrandr --output LVDS1 --fb 992x736
xrandr --output LVDS1 --pos 16x16
replace LVDS1 with your screen name from xrandr.
This works with latest intel driver from xorg-edgers on a netbook..
and the transform and panning options in xrandr sound promising
another page suggests
I have seen a couple of resources online suggeting to do something like (for
top, bottom, left and right):
$ xrandr --output <device> --set TOP 20
Changing 20, until you get it right.

It is overscan issues but haven't found anything that helps. Tried to
adjust tv but no option for that.

hmm, it sounds as if your TV may be cutting off the edge of the display
and you need to adjust your overscan values to tell Linux not to use the
very edge of the display.
I don't use xfce, so I'm not sure exactly how you would do it using it's
tools, but look into the command line xrandr tool, I think it lets you set
things like this.
I've also seen that some TVs let you disable the overscan mode, so you may
want to poke around in it's menus, specifically looking for picture mode
options. When we used large TVs at Scale for hallway displays, we had to do
this, but with my TV at home, I don't.

When the system comes up I get the desktop. I was able to find a way to
get
to the display settings and laptop is the only display there and there is
no way to turn it off.
Just to be clear I am using a 42" Hidef LCD Sanyo TV through one of the
HDMI ports.
When you see the screen on the left you see icons for Home, DVD, Attached
USB Hard Drive but these are cut down by 50%. I can see ome of Home if you
understand.
What I don't see is the top menu bar where the close,minimize and maximize
sits or even the button at the far upper right that you can open the drop
down menu for logout and shutdown. It is there because if I move the mouse
up that way and slowly to the right I can get it to open at times. Like
reaching in the dark.
All I want to do is shrink all of that down so it fits on the screen. I
have a ton of resolutions available in the Display settings app but none
of them help. All they do is make what I see smaller or larger. I also
tried to change the settigs on the TV's (Sanyo)menu but all that does is
make the entire screen smaller or larger and I still see half of the
icons.
I am going to try everyone's suggestion as I want this to work as it was
to
be my media center besides a pc for my Granddaughter to use

Not sure if this is the fix, but I had to turn off my laptop screen when
docked. Otherwise my monitors were overlaid and would not display.
("System Settings - Displays", ensure laptop screen is off)
